HSD3B1 | bioCADDIE Data Discovery Index

Dear DataMed user: DataMed prototype(v3.0) is being developed for the NIH BD2K Data Discovery Index (DDI) by the bioCADDIE project team. DataMed, once completed, will be of use to the scientific community to allow users to search for and find data across different repositories in one space.
We are soliciting your feedback to help us shape DataMeds' future development. Please take a moment to answer this brief Survey Form and give us your thoughts. We believe your voice will be a critical addition to the development of the bioCADDIE prototype.
Thank you, from the bioCADDIE team.

Description:
R, SCARB1, FDFT1, FDPS), steroidogenesis (Cyp11a, HSD3B1, SC4MOL) and testes development (INSL3, INHA). 2-EH caused minor repression of some of the genes in the TMD pathway. This was rationalised on the basis that 2-EH, a DEHP metabolite, is also a weak PPARα agonist. It has been shown that in utero treatment with DBP will repress the genes from fetal testes involved in steroidogenesis and that this effect is associated with direct DBP-mediated binding of PPARα to the promoters of these genes (Plummer et. al. 2010). TOTM did not cause a significant repression of genes in the TMD pathway. Based on these data, it is highly unlikely that TOTM will cause testicular dysgenesis in rats. Rats were exposed to TOTM in utero by the administration of daily oral gavage doses to pregnant dams between gestational day 12 and 19. The foetal testes were obtained by micro-dissection and prepared to facilitate the isolation of RNA, which was subsequently analysed using whole rat genome microarrays....

Description:
ogenesis including LHCGR, INHA, STAR, CYP11A1 and HSD3B1 also down-regulated. BMP6 also reduced expression of NR5A1 encoding steroidogenic factor-1 known to target the promoter regions of the aforementioned genes. Real-time PCR confirmed these findings and also revealed a marked reduction in expression of INSL3 receptor (RXFP2). Secretion of INSL3 protein and androstenedione were also suppressed suggesting a functional link between BMP and INSL3 pathways in controlling androgen synthesis. Theca interna cells (TC) were isolated from adult bovine ovaries obtained from the slaughterhouse. TC pooled from approximately 50 individual 4-6mm follicles were plated out in in 24-well plates (0.5 x106 viable cells/ml/well) and cultured for 6 days under defined serum-free conditions with treatments present on days 3-6 inclusive. TC were treated for 4 days with BMP6 (10 ng/ml) under both basal and LH-stimulated conditions (± 160 pg LH/ml). These dose-levels o...
